The Broken Road by A.E.W. Mason — Read

The month was over before Linforth at last steamed out of the harbour at Marseilles. He was as impatient to reach Bombay as a year before Shere Ali had been reluctant. To Shere Ali the boat had flown with wings of swiftness, to Linforth she was a laggard. The steamer passed Stromboli on a wild night of storm and moonlight. The wrack of clouds scurrying overhead, now obscured, now let the moonlight through, and the great cone rising sheer from a tempestuous sea glowed angrily. Linforth, in the shelter of a canvas screen, watched the glow suddenly expand, and a stream of bright sparkling red flow swiftly along the shoulder of the mountain, turn at a right angle, and plunge down towards the sea.

The bright red would become dull, the dull red grow black, the glare of light above the cone contract for a little while and then burst out again. Yet men lived upon the slope of Stromboli, even as Englishmen -- the thought flashed into his mind -- lived in India, recognising the peril and going quietly about their work. There was always that glare of menacing light over the hill-districts of India as above the crater of Stromboli, now contracting, now expanding and casting its molten stream down towards the plains.
